Tubes and Profiles for Heat Transfer – from Prototype to Series

ARUP Alu-Rohr und Profil GmbH, based in Dortmund, specializes in the development and production of high-frequency longitudinally welded thin-wall tubes and profiles made of aluminium and brass. The company offers more than 300 profiles with existing tooling and develops custom cross-sections for heat transfer applications on customer request – from initial design drafts through prototypes to series production. The products are used in radiators and heat exchangers, including at manufacturers of industrial engines as well as in the automotive industry, power engineering and HVAC (heating, ventilation and air conditioning). The Dortmund site houses production, a testing and validation center with engineers, metallurgists and heat transfer specialists, and administration. Weld seam integrity is continuously monitored in real time. The quality management system is certified to IATF 16949, ISO 9001, ISO 14001, ISO 45001 and ISO 50001.
